Abstract of the Disclosure This invention relates to a process for the preparation of finely divided, stable and relatively low viscosity dispersions of ionic polyisocyanate polyaddition products in compounds having hydroxyl groups by reacting (1) organic polyisocyanate with (2) compounds having primary and/or secondary amino groups and/or primary hydroxyl groups in (3) compounds having at least one hydroxyl group, with the proviso that compounds (3) have secondary hydroxyl groups if compounds with primary hydroxyl groups are used as compound (2), and further characterized in that at least one of the components (1) or (2) has groups which are ionic and/or capable of salt formation.
